Two bugs fixed:
1. SDI capture sidecar never had /dev/blackmagic bound — ffmpeg opened the
decklink input inside a container with no device nodes, so frame=0.
Fix: local spawns now push '/dev/blackmagic:/dev/blackmagic' onto Binds
when source_type='sdi'.
2. recorders.js always spawned sidecars against the local Docker socket
(zampp1), even when a recorder's node_id pointed at zampp2 (where the
card is). Fix: resolveNodeTarget() looks up the recorder's cluster node;
if it's a different hostname the sidecar is spawned via a new
POST /sidecar/start endpoint on the remote node-agent.
node-agent gains three new routes (all talk to the local Docker socket):
POST /sidecar/start — create + start container (host network,
privileged, /dev/blackmagic bind for sdi)
DELETE /sidecar/:id — stop + remove
GET /sidecar/:id/status — inspect + poll capture service
docker-compose.worker.yml: add /var/run/docker.sock and LIVE_DIR to
node-agent so it can spawn sidecars, and document build-capture prerequisite.: docker-compose.worker.yml

# Wild Dragon MAM — Worker Node Stack
|
|
# ─────────────────────────────────────
|
|
# Deploy on any machine you want to join the cluster as a worker.
|
|
# The primary stack (mam-api, db, redis) continues running on TrueNAS.
|
|
#
|
|
# Required env vars (set in .env.worker or export before running):
|
|
# MAM_API_URL URL of the primary MAM API e.g. http://10.0.0.25:47432
|
|
# NODE_TOKEN Bearer token from the primary's Tokens page
|
|
# NODE_IP Host LAN IP to report (set by onboard-node.sh)
|
|
#
|
|
# Optional hardware overrides (if Docker can't see /dev directly):
|
|
# GPU_COUNT Number of NVIDIA GPUs on this node (default: auto-detect from /dev/nvidia*)
|
|
# BMD_COUNT Number of Blackmagic DeckLink cards (default: auto-detect from /dev/blackmagic/)
|
|
# BMD_MODEL Marketed card name (e.g. "DeckLink Duo 2") — drives the port-diagram UI
|
|
#
|
|
# Optional env vars (needed only if starting the worker or capture profiles):
|
|
# REDIS_URL, DATABASE_URL, S3_ENDPOINT, S3_BUCKET, S3_ACCESS_KEY, S3_SECRET_KEY
|
|
# BMD_DEVICE_0 DeckLink device path (default: /dev/blackmagic/dv0)
|
|
# BMD_DEVICE_1 DeckLink device path (default: /dev/blackmagic/dv1)
|
|
# LIVE_DIR Host path for HLS live segments (default: /mnt/NVME/MAM/wild-dragon-live)
|
|
#
|
|
# Profiles:
|
|
# (default) node-agent only — cluster visibility + hardware heartbeat
|
|
# --profile worker + CPU/GPU job worker (proxy generation, transcoding)
|
|
# --profile capture + SDI capture service (requires Blackmagic DeckLink card)
|
|
#
|
|
# To enable GPU transcoding, also apply docker-compose.gpu.yml:
|
|
# docker compose -f docker-compose.worker.yml -f docker-compose.gpu.yml --profile worker up -d
|
|
#
|
|
# NOTE: The node-agent mounts /var/run/docker.sock to spawn on-demand SDI
|
|
# capture sidecars when the primary mam-api routes a recorder to this node.
|
|
# Build the capture image before first use:
|
|
# docker compose -f docker-compose.worker.yml build capture
|
|

# interfaces, GPU devices and DeckLink cards without bridging tricks.
